M. Faber, J. Greensite, and S. Olejnik
TL;DR
This paper derives an effective action for strong-coupling lattice SU(2) gauge theory in three dimensions, demonstrating that center vortices naturally emerge as stable saddlepoints, highlighting their potential role in confinement.
Contribution
It introduces a long-range effective action at strong coupling that reveals center vortices as stable saddlepoints, advancing understanding of non-perturbative phenomena.
Findings
Center vortices are stable saddlepoints of the effective action.
The effective action is derived explicitly for D=3 SU(2) gauge theory.
Center vortices may play a key role in confinement mechanisms.
Abstract
A long-range effective action is derived for strong-coupling lattice SU(2) gauge theory in D=3 dimensions. It is shown that center vortices emerge as stable saddlepoints of this action.
